I agree that NI changed DAQ, but just look at the huuuuge advancedments in LabVIEW in the last 3 versions! Sure, I was a big fan of 5.1.1 back in the day, but now I can't live without my project explorer. I think that this arguement is more about whether LabVIEW is a general purpose programming language, not whether NI is trying to change the world.
Also, just because NI "successfully changed DAQ" doesn't mean that they have a lack of ambition - I find it offensive to call the fantastic strides NI has made as a "lack of ambition". Sure, they may not have a world domination attitude, but they're certainly not unambitious - you've got to give them that...
